Abstract
A head-mounted device may include a first display having a first projector and a first waveguide, a second display having a second projector and a second waveguide, first and second cameras, an optical sensor that couples the first waveguide to the second waveguide, and position sensors mounted to the first and second cameras and the optical sensor. The optical sensor may gather image sensor data from first image light propagating in the first waveguide and second image light propagating in the second waveguide. The cameras may capture real-world images. The position sensors may gather position measurements. Control circuitry may calibrate optical misalignment in the device by adjusting the first and/or second image light based on the image sensor data, the position measurements, and/or the world light.
